[目的] 开展城市生态安全格局构建和主要生态廊道识别研究，为城市国土空间规划中生态格局的优化提供科学参考。[方法] 以江西省抚州市为研究区，选取土地利用因子，水土保持功能重要性以及生态敏感性等多种因子构建最小累积阻力模型，依据生物多样性维护功能重要性评价、全域水文分析、生态保护红线以及自然保护地识别生态源地，依托MCR模型和ArcGIS中的空间分析工具开展研究。[结果] ①抚州市整体生态环境良好，水土保持功能极重要性区所占比例为49.97%，主要集中在抚州市中部地区，以黎川县、乐安县、宜黄县和南丰县为主；抚州市生态敏感性极重要区所占比例为1.39%； ②生态源地面积3302.34 km2，所占比例为17.57%，以抚州市东部和西南部为主； ③以全域的生态要素和地形地貌等为基底，抚州市呈现出“一轴、两屏、多廊、多节点”的生态安全格局。[结论] 结合生态源地、生态廊道和生态节点，形成完整、系统的生态保护格局和开敞空间网络体系，维护抚州市生态安全和生物多样性。
[Objective] An urban ecological security pattern were constructd to identify the main ecological corridors in order to provide a scientific reference for optimizing the ecological pattern in urban land spatial planning. [Methods] Fuzhou City of Jiangxi Provicne was used as a research area. A minimum cumulative resistance (MCR) model was constructed by selecting various land use factors, soil and water conservation function importance, and ecological sensitivity. The importance of a biodiversity maintenance function, global hydrological analysis, ecological protection red line, and natural protection were used to identify ecological sources using the MCR model and spatial analysis tools in ArcGIS. [Results] ① The overall ecological environment of Fuzhou City was good. The proportion of areas with extremely important soil and water conservation function was 49.97%, mainly concentrated in the central area of Fuzhou City, mainly Lichuan County, Le’an County, Yihuang County, and Nanfeng County. The proportion of extremely important ecological sensitivity was 1.39%; ② The ecological source area was 3 302.34 km2, accounting for 17.57%, mainly in the east and southwest parts of Fuzhou City; ③ Based on the ecological elements and topography of the entire region, Fuzhou City presented an ecological security pattern of “one axis, two screens, multiple corridors, and multiple nodes”. [Conclusion] By combining ecological sources, ecological corridors, and ecological nodes, a complete and systematic ecological protection pattern and an open spatial network system can be formed to maintain the ecological security and biodiversity of Fuzhou City.
